Sure, you work out to tone up and get fit. But sometimes...you just want to torch calories. Stephanie Vitorino, a group fitness manager at Equinox, swears these exercises will burn fat ASAP.

The Reverse Lunge

The Reverse Lunge

Hold a eight to 10-pound weight in each hand and hinge forward at the hips as you step back into a lunge. This uses more of your glutes and lower body—and using more of your bod burns more calories. Then extend your arms out at your sides into a rear fly. Hold for one second and lower your arms. Do 10 reps with each leg.

The Burpee Pushup

The Burpee Pushup

This move builds lean muscle by using your own body weight. Instead of just doing a pushup, start from a standing position, hop back into a pushup, and then hop back up to a standing position. Do 10 reps.
